How to join Slack workspaces Another way to add workspaces to Slack is to accept an invitation from a member. You receive the invitation via email, and accepting it launches Slack.

As a business-oriented chat platform, Slack is prepared to help control access to all workspaces. Here is how to remove someone from your Slack workspace.

It enables Slack users to send an invite to someone outside of their Slack “workspace,” which, when accepted by the other party, allows direct messages to be exchanged in the chat app.
